INVENTOR. FRANCIS J. GEDMINAS A TToe/vz Y Patented Sept. 11, 1951PATTERN FOR MOLDING ORNAMENTAL PLASTIC VENEER Francis J. Gedminas,Philadelphia, Pa Application May 19, 1949, Serial No. 94,208- -'3Claims. (01. 25118) My invention relates to a device for forming plasticveneer upon walls or surfaces for simulating stone, bricks, blocks, orthe like.

An important object of the invention is to provide a device which willpermit of the veneered surface having an ornamental or colored coating,without applying the same to the artificial mortar joints.

A further object of the invention is to provide a pattern, for producingthe design in the veneer,

which pattern is of simplified construction and has a large range ofadjustments for producing difierent shapes.

A further object of the invention is to provide a pattern which isflexible and may be applied to a flat or curved wall surface.

Other objects and advantages of the inventio will be apparent during thecourse of thefollowing description.

In'the drawings, forming a part of this appli-* cation, and in whichlike numerals are employed to designate like parts throughout the same,

Figure 1"is a fragmentary side elevation of a wall preparatory toapplying the plastic veneer,

Figure 2 is a side elevation of the assembled pattern, parts brokenaway,

Figure 3 is a side elevation of the plastic Veneer after being appliedto thewall, the assembled pattern being in place, parts broken away,

Figure 4 is a transverse section taken-on line 4-4 of Figure 3,

Figure 5 is an enlarged side elevation of one of the pattern strips,

Figure 6 is a transverse section taken on line 66 of Figure 2,

Figure 7 is a side elevation of the completed plastic veneer, with thepattern removed, parts broken away,

Figure 8 is a side elevation of the plastic veneer showing the patternin place therein and adjustecl to form a brick or block design, partsbroken away, and,

Figure 9 is a transverse section taken on line 9-9 of Figure 1.

In the drawing wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral Ill designates avertical wall which is illustrated as formed of wood, although it may beformed of other suitable material. Secured to the outer face of thisWall by any suitable means, such as staples is a foraminous metal sheetH, which may be a wire mesh or expanded metal lath.

In accordance with my invention, I provide a pattern which includes aplurality of strips l2,

i3 and I4, which are identical except that'they and throughout itsentirev length with holes l5 which extend through the outer face of thestrip but terminate short of its inner face, and these holes areequidistantly spaced. .Ea'ch strip is tapered in cross-section anddecreases in width inwardly, providing inclinedsides I6, and outer andinner faces I! and I8, which are parallel and vertically disposed inuse. These strips are adjustably and detachably connected by staples [9which are interchangeable and adapted for insertion within the holes l5,and are readily removable therefrom. The staples project outwardlybeyond the outer faces I! so that they may be conveniently manipulated.The strips are preferably formed of-rubber reinforced with fabric andare somewhat flexible, which will permit them to be applied to a fiatwall or to a curved surface like a cylindrical pillar. Figure 2 showsthe strips assembled and connected for producing a rough cutstonepattern.

In the practice of the method, a plastic veneer 20 is applied to theforaminous sheet ll secured to the vertical wall I0. The mix 'for"theplastic veneer is suitably stiff so that it will not slouch prior tosetting. This plastic veneer may contain a mixture of sand, sodiumchloride, lime and water, the volumes being optional except that the mixshall be suitably stifi, for the purpose stated. Any other suitable mixmay be employed. The veneer 2B is applied by trowelling or the like.After the plastic veneer 20 is thus applied to the vertical wall, theindividual pattern strips are pressed into the plastic'veneer 20, andarranged to produce the desired design. The design shown in Figures 2and 3 simulate rough cut stone. The strips 12 may be generallyhorizontally-arranged while the'strips l3 and I4 may be diagonallyarranged. After the strips are pressed into the veneer 20 so that theirouter faces are substantially flush with the outer face of the veneer,the strips are connected by the staples I9, which are forced intoselected holes l5. It is obvious that since the holes extend throughoutthe entire length of the strips and are equidistantly spaced, the stripsmay be arranged in varied relation to each other. By connecting thestrips they produce a unitary pattern. The assembled and connectedstrips constituting the pattern may be held stationary in position, byany suitable means, such as wood strips S held in place by clamps. Theunitary pattern thus held in place will oppose any slouching tendency ofthe veneer, before it sets. The outer face of ing mortar joints.

the veneer with the pattern strips embedded within the veneer may besuitably worked by the conventional trowel or by a vibrating trowel. Ifit is desired to provide the veneer 20 with an ornamental face, crushedstone, or crushed glass or the like, is applied to the outer face of theveneer, before it sets and while the pattern is in place, and this faceworked into the veneer. The crushed :stcnefor the like may be appliedbytrowel or an air blast containing the crushed stone therein. Instead ofapplying the solid particles to the outer face of the veneer, such outerface may be colored or tinted'by paint-cor like material. The advantagein applying the coating to the outer face of the veneer, while thepattern is still in place, is that the coating "of solid particles orpaint is kept out of the egrooves formed by the pattern strips. Theveneer is then allowed to set or harden, after which the pattern stripsare individually disconnected from each other by: theremoval of'the'staples, and separated f-irom the lset veneer, providing grooves '22having thetfdesi'gnzof the pattern andsimulat- The outer zface of theveneer "will then simulate irregular-cut stone having f mortar joints.
